The Black Diamond Agent AvaLung is streamlined enough to ride the lift up for sidecountry laps, yet has enough room for avy-tool essentials on longer day missions in the backcountry. In the event of an avalanche burial, the built-in AvaLung increases your chance of survival by pulling fresh air from the surrounding snowpack. Our diagonal ski carry cable is ultra-secure for hikes, and the innovative HiLo helmet holder gets your lid off when you're really sweating for those turns.
